旅游归来，照片太多了。不想把原大小的照片和人分享，又懒的安装什么图像处理软件，于是用python写个脚本批量处理一下，一蹴而就：

import Image, os def resize(fname):    img = Image.open(fname)           ratio = float(img.size[0]) / img.size[1]    width = int(ratio > 1 and 1024 or 1024 * ratio)    height = int(ratio > 1 and 1024 / ratio or 1024)        resized_img = img.resize((width, height), Image.ANTIALIAS)    basename, extension = os.path.splitext(fname)    resized_img.save(basename+'_resized.jpg') if __name__ == '__main__':    path = os.path.abspath(os.curdir)    dirList = os.listdir(path);    for fname in dirList:        basename, extension = os.path.splitext(fname)        if extension.lower() == '.jpg':            resize(fname)
